Before you switch

  • Free to use, not free to run. The licence costs nothing, but self-hosting needs a server (often $5 to $40 a month) and someone to install updates and keep backups.
  • Open core means the main product is open source but some features, usually for larger teams, need a paid licence.
  • Hosted versions exist for many of these, run by the makers. They cost money but save the upkeep, and you can still move to your own server later.
  • Licences differ. MIT and Apache allow almost anything. GPL and AGPL require you to share changes you make to the code; for normal business use, that rarely matters.
